We will use chain rule for this differentiation: First, differentiate the outer bracket -> 4 (6x^2 + 7x)^3 Now, differentiate the term inside bracket and multiply with the term we got from previous step: 4 (12x+7) (6x^2 + 7x)^3
GDP, the most widely used measure of economic growth of a country, has increasingly been looked at with a sceptical eye in economic circles these days. Comment on one such criticism.
One of the reasons why GDP has been criticised is because it only accounts for the production of those goods and services whose value can be monetised in a certain way. For eg: household work done by a family member would not get accounted for in GDP. This creates an issue in a lot of countries like India where a major part of female population traditionally holds the responsibility of household rearing but none of their work gets counted in the country's total output.
There are 19 girls in a class. This is 3 more than 4 times the boys in the class. Calculate total strength of the class.
Let G = the number of girls in the class = 19 B = number of boys T = total strength of the class = B + G Key to solving this question is convert the given information in an equation format. 4 times number of boys = 4B 19 = 3+4B => B = (19-3)/4 => B = 16/4 => B=4 T = B+G = 4+19 = 23 Hence total strength of the class is 23
